Abstract
A dual tapered dovetail shaped mortise is formed within a joist to receive a dual tapered dovetail shaped tenon extending from a beam. Laterally oriented cavities are disposed within opposite faces of the mortise to receive correspondingly configured ridges formed integral with the mating tenon. The resulting frictional interlock between the mortise and the tenon created by two forces acting in opposition to one another rigidly secures the beam to the joist without play therebetween. The ridges, mating with the corresponding cavities, affords use of the resulting joint in any plane from horizontal to vertical without danger of separation.
